Description:	Tideglusib is an irreversible GSK-3 inhibitor with IC50s of 5 nM and 60 nM for GSK-3βWT (1 h preincubation) and GSK-3βC199A (1 h preincubation), respectively.
In Vivo:	Tideglusib (NP12) treatment correlates with an increase of 46% as an average in the inhibitory phosphorylation of GSK-3β at Ser-9 in the brains of APPsw-tauvlw mice, and the levels of the inactive from of the enzyme in NP12 treated mice are comparable to those found in wild-type littermate controls (p=0.893) (n=6-8 for each treatment). NP12 treatment results in significantly decreased phosphorylation at the putative GSK-3β-directed sites Ser-202 (CP13) and Ser-396/404 (PHF-1) in 15-month-old mice by more than 60% (p=0.023 and p=0.024, respectively)[2]. Injection of Tideglusib (NP031112) (50 mg/kg) into the rat hippocampus dramatically reduces kainic acid-induced inflammation, as measured by edema formation using T2-weighted magnetic resonance imaging and glial activation and has a neuroprotective effect in the damaged areas of the hippocampus[3].
In Vitro:	Tideglusib (NP12) is a small heterocyclic thiadiazolidinone (TDZD) derivative, which is an ATP-non competitive inhibitor of GSK-3β with an IC50 value in the micromolar range[2]. Incubation of both astrocyte and microglial cultures with Tideglusib (NP031112) completely abrogates the induction of TNF-α and COX-2 expression after glutamate treatment. These effects of NP031112 are not caused by a loss of cell viability, because the 24 h exposure of astrocyte and microglial cells to this TDZD does not modify cell viability[3].

Cat. No.	Product name	Field of application
DC82301	IC-8	IC8 is an ionizable cationic lipid. It has been used in combination with other lipids for the formation of lipid nanoparticles (LNPs). Immunization with severe acute respiratory coronavirus 2 (SARS-CoV-2) spike glycoprotein mRNA in IC8- and manganese-containing LNPs induces IgG responses to SARS-CoV-2 Delta and Omicron variants in mice.1 Administration of mRNA encoding B7-H3 X CD3 bispecific T cell engaging (BiTE) antibodies in IC8-containing LNPs reduces tumor growth in MV4-11 and A375 mouse xenograft models.
DC75721	CL2A-SN38 (Govitecan)	CL2A-SN38 is a SN38 derivative with a peptide-linker which can easily react with antibody to form an antibody-drug conjugate (ADC). CL2A-SN-38 is composed of a potent a DNA Topoisomerase I inhibitor SN-38 and a linker CL2A to make antibody drug conjugate (ADC). CL2A-SN-38 provides significant and specific antitumor effects against a range of human solid tumor types. CL2A is a noncleavable complicated PEG8- and triazole-containing PABC-peptide-mc linker. CL2A is cleavable through pH sensitivity, giving rise to bystander effect, and binds the antibody at a cysteine residue via a disulfide bond. .
DC47877	tri-GalNAc-COOH (acetylation)	tri-GalNAc-COOH acetylation is the acetylated and modified form of tri-GalNAc-COOH. tri-GalNAc-COOH acetylation can be used for the synthesis of LYTAC.
DC46965	Tri-GalNAc-COOH	tri-GalNAc-COOH is an asialoglycoprotein receptor (ASGPR) ligand that can be used for LYsosome TArgeting Chimera (LYTAC) research.
